0.3.0

New decompression modes:

tarGzExpander

It is no longer required to use an intermediate file with tarGzExpander.

// this will use an intermediate file (defaulting to /tmp/tmp.tar)
tarGzExpander(tarGzFS, "/blah.tat.gz", tarGzFS, "/tmp" );

// this will use an intermediate file too
tarGzExpander(tarGzFS, "/blah.tat.gz", tarGzFS, "/tmp", "/tmp/my_temporary_file.tar" ); 

// this will do a direct gz->tar->filesystem expanding, using no intermediate file
tarGzExpander(tarGzFS, fileJustBigEnoughForSPIFFS, tarGzFS, "/tmp", nullptr );
